Hello there!

I tried the backup script for mysql/mariadb and the output files are only 1KB.
There are no errors during runtime, except

 create Backup for Database on Container:
  * /run/secrets/mariadb_database DB on mariadb_baikal
./mariadb_backup.sh: line 58: /docker/backup/database/mariadb/mariadb_baikal-/run/secrets/mariadb_database-202111231913.sql.gz: No such file or directory
mysqldump: Got error: 1045: "Access denied for user 'root'@'localhost' (using password: YES)" when trying to connect
ls: cannot access '/docker/backup/database/mariadb/mariadb_baikal*.gz': No such file or directory

But this error only happens with two different containers, there are no errors with the other containers, although i deployed them the same way, so i don't get it, why an error occurs with these two containers.

Do you have an idea what to do?

Greetings

HI

Kannst du ein Vidoe machen wie man das hier benutzte am besten das https://www.laub-home.de/wiki/Docker_Backup_und_Restore_-_eine_kleine_Anleitung#Backup_via_Script

does these scripts also work for docker in synology nas? I can´t find the path /usr/local/sbin there - so I tried to start a script from somewhere else but nothing happened

Hallo

danke für das Script, allerdings bekomme ich einen Fehler und der dump ist leer.

Start 202112060549 Backup for Databases: 

 create Backup for Database on Container:
  * meine_db

/usr/lib/postgresql/9.5/bin/pg_dumpall: option requires an argument -- 'U'
Try "pg_dumpall --help" for more information.

202112060549 Backup for Databases completed

wenn ich in den User hardcoded in das Script schreibe klappt es:

docker exec $i pg_dumpall -c -U postgres | gzip > $BACKUPDIR/$i-$TIMESTAMP.sql.gz

LG opaque

Hello,

I just used the script with the Linuxserver mariaDB container and got this error:
" create MYSQL Backup for Database on Container:

• DB on mariadb
  Usage: mysqldump [OPTIONS] database [tables]
  OR mysqldump [OPTIONS] --databases DB1 [DB2 DB3...]
  OR mysqldump [OPTIONS] --all-databases
  OR mysqldump [OPTIONS] --system=[SYSTEMOPTIONS]]
  For more options, use mysqldump --help"

I added --all-databases to the mysqldump within the script and then it works.
